nus app to send uint8_t

[seanbites]

Hello,

As far as I can tell, the NUS app sends a signed char of value -127 to 127 in decimal. Is there a way to use the stock UART application to send an unsigned byte of value 0 to 255? In other words, can I send a string such as : {0xDE, 0x02, 0XF5, ...} ?

edit to clarify: I'm trying to send {0xDE, 0x02, 0XF5, ...} from the mobile application to a peripheral device. The mobile application can only send ascii characters, so the range of values that can be sent is very limited. Is there a way to send values from the mobile application that are not ascii (say between 0x00 and 0x30)? Hopefully without having to modify the mobile application.

Thank you very much.

They're just bits, you can interpret them any way you like, just cast the uint to whatever's needed by the NUS service and send it.

The mobile application may only let you type in ascii characters, but the NUS service can send any byte from 0x00-0xff. You just write the byte, it sends it.

Ok thanks, I'll check that out :)
